 You've got that totally bottom about face-
'When the car begins to accelerate, some new forces come into play. The rear wheels exert a force against the ground in a horizontal direction; this makes the car start to accelerate. When the car is moving slowly, almost all of the force goes into accelerating the car. The car resists this acceleration with a force that is equal to its mass multiplied by its acceleration. A car accelerates rapidly at first. As it starts to move, the air exerts a force against the car, which grows larger as the car gains speed. This aerodynamic drag force acts in the opposite direction of the force of the tires, which is propelling the car, so it subtracts from that force, leaving less force available for acceleration.
Eventually, the car will reach its top speed, the point at which it cannot accelerate any more. At this point, the driving force is equal to the aerodynamic drag, and no force is left over to accelerate the car'.

I don't think Eddie actually owns (or has ever owned) a car, otherwise he'd know clearly how cars accelerate as has been explained

John, agreed! You know when your head goes into "psychology mode" just trying to figure out why someone is the way they are and why they say certain things, sorta thing? It's hard to explain, but the guy baffles me lol
Must do a lot of cringing then Graham

Hey guys, I think some of you are breaking maths in here.
0-50 time does not equal 50-100 time....

I have a 206 gti with a turbo conversion. Is it as fast as a Turbo Porshe... most probably not. Would i swap it for a Porshe... no. To me its a pain in the ar*e but i still love it and would never sell it on. Its all about the hobby for me, lets be honest, what engine is likely to need a rebuild first? Get what you pay for at the end of the day, try to not take it too seriously

NOTE ALL TIMES AND SPEEDS ARE IN KPH ON THIS POST AS ??MPH??WOULD BE TOO FAST FOR BRITISH ROADS..M<Look guys chill out right.....but sebs right the car will get from 50-100 sooner than from 0-50...now the weight of numbers seems to grow against my theory so jump in your cars and you will see that higher speed acceleration(the 50-100)happens sooner than the lower from stand still 0-50 Time....unfortunately mines off the road for a couple of weeks but i look forward to testing the theory as im sure its faster up top???
If im wrong i will hold my hands up and eat my hat but im sure in a car the same as mine..a 2002.138gti it eats up the 50-100 in a flash where it takes longer to do 0-50THATS 50!...
We can try to baffle each other with science but the best test is to drive it...dont forget tho..the different models will show different results...

We don't need to drive it Eddie, we can just go off what data the manufacturers publish.
On your theory, it should take the same amount of time accelerating from 0-10mph as it does 60-70mph or even 30-40mph or is it quicker acceleration the faster you go?
When you see it in black and white, you might understand

Well this says it takes thirteen and a half seconds to go from 60 to 100mph..
Thats 13.5secs from 60-100mph..
NO CHANCE.

It also says its a 1999 model and has 180BHP.

Pagani Zonda Cinque 7.3L
0 to 60 mph (96.6 kph): 3.3 secs
0 to 100 mph (160.9 kph): 9.4 secs
Ariel Atom Mugen
0 to 60 mph (96.6 kph): 2.9 secs
0 to 100 mph (160.9 kph): 6.9 secs
Ford Fiesta 1.6 Zetec S
0 to 60 mph (96.6 kph): 9.6 secs
0 to 100 mph (160.9 kph): 26.0 secs
Can you see a pattern emerging Eddie

WELL THEN.....
As much as it seems like madness and i hate to admit it it seems like the 60-100 times are as slow as you claim..
But i reserve final judgement until i can get mine moving and see for myself...i know im persistant..but you have to be these days...
It just seems like a lifetime to raise up that poxy 40mph..
13.5secs on the 206 180...of course all cars are different but it seems luke your argument stands...
now wheres that hat?¿????????????swinexdaxmxxxfuxktwxxxxcuxxx:)

I don't think he said that, & even if he did it doesn't change the fact that your wrong.
